PROCESS OF PRESERVING FISH.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed January 24, 1906. Serial No. 297,6;7.

To all whom it may concern:

Be it known that I, RENE Manor, a citizen of the Republic of France, and resident of Paris, in the said Republic, engineer, have invented a new and useful Improved Process of Preserving Fish, ofwhich the following is a specification.

It is a question of prime importance in the fishing industry, particularly for .cod fishing, which involves long sojourns in places far from port and the use of a large quantity of bait, that it should-be possible to carry on board an amount ofbait which shall not only escape putrefaction but shall have at the time of use all the appearance.

of fresh fish, so that it may be well fitted for its purpose.

The present invention relates to a process whereby these ends ma be attained.

In the accompanying drawing an appa-. ratus is illustrated diagrammatically which may be em ployed to carry out my invention.

a is a closed .room or chamber furnished with a d'oo Z). In this chamber the fish (Z The chamber or room a from aTchamber 6 through any opening it. The chamber c 'is preferably of glass and is furnished with electrodes 0*. A fan or blower f is connected to the chamber 0, which fan or blower is driven by a belt 9. A pipe It leads into the center of the fan or blower f, in which pipe are located one or more air inlets The sulfurous anhydrid is furnished from a metallic bottle 7' where it may be retained at high pressure and ina liquid state. The sulfurous anlzydrid isfed in proper quantities to be mixed with the air in the pipe h.

The invention consists in first exposing for a certain time the fish which is to be preserved to the action of a gaseous mix-.- ture obtained by causing air mixed with sulfurous anhydrid to traverse a. space i wherein the mixture is subjected to the action of one ozonizer the silent electric discharge or electric sparks produced by an electric current of high voltage, or the silent electric discharge and electric sparks concurrently. The fish thus treated are then dried in air.

Care should be taken that the gaseous.

. the action of the silent electric discharge or of electric'sparks, may be used.

In practice I preferably use a gas composed of sulfurous anhydrid and atmospheric air of about ten per cent. strength, or say about 27 i grams of sulfurous anhydrid toa cubic meter of atmospheric air, which gas is subjected to the action of an ozonizer and the fish to be preserved may be treated with the gaseous mixture thus obtained for about twenty four hours.

What I claim as my invention and desire to secure by Letters Patent, is Y Aprocess for preserving fish, especially for use as bait, consisting in submitting it first, in a closed room, to the action of a' gaseous, mixture obtalned by causing air mixed with sulfur-ens anhydrid to traverse a space wherein the mixture is subjected to tlie'action of an ozonizer, and then drying the fish in the air.

In testimony, that I claim the foregoing as nay-invention, I have signed my name in presence of two w tnesses, this'12th-day of January, 1906.
